Wang Gang: Nothing, games can develop intelligence!

Me: Yes, games can develop intelligence, but they are also harmful to people! You'd better stop playing.

Wang Gang: Dude, be loyal and help me keep a secret!

Me: I can keep your secret, but don't play games in the future, it will affect your study.

Wang Gang: Well, it's a good thing you reminded me in time, otherwise I will regret it sooner or later.
